Magnox Berkeley NPP, UK

Cyclife Aquila Nuclear & Magnox teams at successful site commissioning

Background

The Chute Silo intermediate-level waste project was set up by Magnox to retrieve waste in the form of irradiated control rods and charge chutes, from a storage silo on the Berkeley nuclear site in UK.

Challenge

35 waste baskets had to be removed from the silo building and transferred to a Ductile Cast Iron Container (DCIC) for further export to an on-site storage facility.

Magnox had a scheme design from a third party for a solution, but Cyclife Aquila Nuclear was not convinced this was the right solution because it was complex and expensive.

Our proposal

Cyclife Aquila Nuclear designed a new solution using « commercial-off-the-shelf » items to reduce cost in manufacturing and cost of actual operation by Magnox.

The solution included a custom-made pintle grab for lifting waste baskets, a shielded cell for de-lidding and loading waste baskets into DCIC, and overhead hoist for loading DCIC on to cross-site transporters.

Customer benefits

  • Pragmatic design for manual operation substantially reduced cost of the project.
  • Robust project management helped beat original programme even with additional scope, enabling Magnox to use the solution ahead of their planned schedule.

Results

  • Cyclife Aquila Nuclear won the NDA Award for « going the extra mile »
  • > GBP 1M cost saving to Magnox’s original budget
  • Three-month programme reduction
